An energy-conserving dynamical model of GRB afterglows from magnetized forward and reverse shocks
Qiang Chen, Xue-Wen Liu
In the dynamical models of gamma-ray burst (GRB) afterglows, the uniform assumption of the shocked region is known as provoking total energy conservation problem. In this work we c…
Unified perspective on single cyclotron electron with radiation-reaction from classical to quantum
Qiang Chen, Peifeng Fan, Jianyuan Xiao
We show a unified physical picture of single cyclotron electron with radiation-reaction, which bridges the classical electron models and quantum mechanical self-consistent field th…
High-order Field Theory and Weak Euler-Lagrange-Barut Equation for Classical Relativistic Particle-Field Systems
Peifeng Fan, Qiang Chen, Jianyuan Xiao
It is widely accepted that conservation laws, especially energy-momentum conservation, have fundamental importance for both classical and quantum systems in physics. A widely used…
Loop Quantum Gravity's Boundary Maps
Qian Chen, Etera R. Livine
In canonical quantum gravity, the presence of spatial boundaries naturally leads to a boundary quantum states, representing quantum boundary conditions for the bulk fields. As a co…
Scaling of Magnetic Dissipation and Particle Acceleration in ABC Fields
Qiang Chen, Krzysztof Nalewajko, Bhupendra Mishra
Using particle-in-cell (PIC) numerical simulations with electron-positron pair plasma, we study how the efficiencies of magnetic dissipation and particle acceleration scale with th…
